Ash "Chrono Number X"

Former Chronos Number X and partner as well as best friend of Naizer. He never actually appeared in the volumes, but it was explained that he was killed by Creed Diskenth.

Ash in the anime

Ash actually does appear in the anime, and it's shown that his weapon is a cane (name unknown), having the ability to split the ground with one hit. This may be a shikomizue (a cane with a sword inside). Another notable detail is that Ash has an "X-shaped" scar between his eyebrows, which is covered by his bandana. Like in the manga, he was killed by Creed, but the scene is actually shown.
